Moderate Islam doesn’t exist and never has. From the very beginning Islam has been a religion of submission, conquest, misogyny, cruelty, hatred and death. The term moderate Islam is a misnomer, a falsehood. Islam is completely uncompromising and always has been and denying that is denying reality.
There are two basic reasons why Muslims in general don’t speak out against the atrocities committed in Islam’s name. First, Islamists who commit these atrocities are theologically correct. Second, they are afraid of the repercussions for them and their families. Islam brooks no opposition, especially by those who are supposed to be believers. Muslims who dare to speak out place themselves and their loved ones in great danger.
